Career
Jamison is a key defender, particularly good against leading players, who has played for several years at the North Ballarat Football Club, with his under-18s football at the North Ballarat Rebels, and then reserves and seniors with the Roosters. Jamison was invited to train with the Carlton Football Club in the 2006/07 offseason, presumably on advice from Carlton assistant coach and outgoing Roosters head coach Gavin Crosisca. Carlton then selected Jamison as a rookie with their second selection in the 2007 American Federation of Labor-Congress rookie draft (17th pick overall).
As a rookie, Jamison began the 2007 season playing with Carlton"s VFL-affiliate, the Northern Bullants.
After the retirement of Anthony Koutoufides, Jamison was promoted to the senior list and made a successful senior debut against Collingwood in Round 18. He began 2008 as a nominated rookie.
Throughout the season, he played primarily on the opposition"s best leading forward, often due to injuries to other key defenders. Jamison played a total of sixteen games throughout the season, missing six through his shoulder injuries.
He routinely tapes his shoulders for games.
At the end of 2008, Jamison was officially elevated to the senior list. In 2010, Jamison was elevated to the club"s leadership group, after playing only 34 games, and captained the side in Chris Judd"s absence in his 37th game, in Round 3 2010 against Essendon. Jamison had a breakthrough season in 2014, becoming proficient as both a defensive stopper and as a damaging rebounder.
